Hi All,
Looking for some help here with a weird problem i'm having. About a month ago my Tahoe randomly had its radiator fan turn on while driving in cold weather (30-40 degree) and not shut off, in addition, the coolant temp would not come above the lowest temp mark on the gauges.
I replaced the coolant temp sensor, and restarted the vehicle and the fan was off and it seemed the coolant temp was now heating up (at least more than the very minimum)
Now, the coolant temp very rarely ever reaches the middle mark for operating temp, it normally only reaches midway between cold and operating temp. We have driven multiple 6hr road trips since then and it almost never has reached operating temp.
Is this a basic thermostat issue? Bad coolant temp sensor? Any advice is greatly appreciated.
